BRYAN Robson has claimed the "strange results season" has arrived as he looks for West Brom to pull off a major surprise against runaway Premiership leaders Chelsea at The Hawthorns tomorrow.

The Albion manager believes the heavy schedule of the leading sides can lead to unexpected outcomes to matches, as demonstrated by Middlesbrough's 3-0 triumph over Jose Mourinho's side.

Robson said: "We are getting close to the time of the season where you get strange results. If you look back two or three weeks, Boro beat Chelsea 3-0 which surprised a lot of people.

"But those sort of results start coming in at this stage of the season. Whether that is because people get a bit tired in certain games or because the big teams are in the Champions League, I don't know.

"But they are there to be beaten and players have always got to believe they can beat them."
